Anecdotal evidence suggests that the HIV/AIDS prevalence rates in several African armed forces are high, with gender inequality rendering female military personnel more vulnerable to the disease. The object of this study was to replicate a successful videotape-based HIV prevention intervention among Nigerian female military personnel in an effort to establish the cross-cultural stability, feasible and cost-effectiveness of this approach in resource-limited countries. Enlisted women (N=346) were recruited from two cantonments in Southwestern Nigeria and randomly assigned to either (a) a 5-session video-based, small group, cognitive-behavioral, HIV prevention intervention or (b) a 5-session, video-based, contact-matched, HIV education control condition. Participants provided self-report of their HIV/AIDS-related knowledge and sexual behaviors at baseline, 3 and 6 months after completing the intervention. The results indicate that the motivational skills-building intervention did not improve participants' knowledge of HIV/AIDS any better than did the HIV education control condition at each assessment period, but it significantly (p<0.05) increased condom use among women in this group by 53.6% at 3-month follow-up. HIV preventive behaviors among women in the motivational skills-building intervention group improved significantly (p<0.01), being 2 and 3 times more, compared to women in the HIV education control group at 3-month and 6-month follow-up assessments. The intervention also significantly (p<0.001) improved behavioral intentions of participants as well as reduced alcohol use before sex by 25% (p<0.01), after 3 months; and number of sexual partners by 12% (p<0.05) after 6 months. Women in the intervention group were five times more likely than women in HIV education control group to suggest that their new male partners use condom. These findings indicate that a videotape-based, HIV prevention intervention is a feasible and effective approach to HIV prevention among female military personnel from sub-Saharan Africa.
